GPU memory tester

Not sure if this is posted before, but like you have RAM testers like “memtest” to check for faulty/failing RAM errors which can causes crashes or even silent data corruption, there is also a GPU memory tester available from the folding@home project:

Folding@home: NVIDIA GPU memory checker

Folding@home: NVIDIA GPU memory checker – Update

MemtestG80 is a software-based tester to test for “soft errors” in GPU memory or logic for NVIDIA CUDA-enabled GPUs. It uses a variety of proven test patterns (some custom and some based on Memtest86) to verify the correct operation of GPU memory and logic. It is a useful tool to ensure that given GPUs do not produce “silent errors” which may corrupt the results of a computation without triggering an overt error.
